The characters are all over 18. Do not try this at home. Or in a strange sea cave.

Kit and Deena ran, hand in hand, down towards the beachline. It was the third day of their vacation and they had explored the more popular beaches in the area and they were searching for the more hidden gems. Sure the ones they had visited had hit all the marks; great views, clear water, soft inviting sand. But they lacked one key element the frisky couple desired; privacy. They slowed as they approached the shoreline. To the left the beach continued down for about a quarter mile until it ran into cliffs. To the right, the cliffs were closer but pushed out into the sea.
Kit and Deena slowed down and at last came to stop in the dark brown sand. Panting, looked around, "Babe-I can't believe we have this place totally to ourselves."
Deena caught her breath and looked around. "I was excited when I didn't see any cars but I thought we would find some people walking around here at least. I mean look at this water-it's fantastic!"
Kit shielded his eyes from the sun and surveyed the beachline, followed the outcropping where it led into the water. Leaning in he saw a dark spot in the rocks. "Babe, I think I see a cave out there." She squeezed his hand in delight and they started wading into the surf towards the it. The locals had warned them away from this area saying that there was a sea witch that lived out here and dragged foolish swimmers to their deaths. Kit and Deena knew beaches; they figured it was probably a riptide. Looking at the beach it was ripe for it. But hey-it kept the locals away and now they were going to get to fuck on the beach and in a real life sea cave! Besides they were experienced in dealing with riptides and always carried emergency inflatables on them when they swam in strange areas.
As they waded deeper and noted that yes-even this further out into the bay there were not even any boats nearby. Hell of a curse they thought to themselves. The cave itself looked fairly deep. Going inside at the current tide level there was plenty of both dry and wet area. It was much wider inside than it looked from the outside and seemed to actually take up a larger portion of the cliffs than they had expected. Excitedly, they rushed into the darkness.
They stopped about 30 feet in. Here there was still plenty of light from the entrance and shallow pools all around them. Deena smiled and walked over to an outcropping on the sand, placing their bags there. She then turned to him demurely first stripping off the light shirt she had over her bikini top, then unclipping her bikini top and tossing it to the cave floor. Kit smiled back as his swim shorts strained to hold in his raging erection and he began to shed his now restrictive clothing. Both now naked, she grabbed his hand and drew him back into the knee-deep water and they began to kiss. They both planned to take this slow as they had all day ahead of them and wanted to make the most of their new playground.
In the darkness of the cave, she stirred. Sulara had lived in the cave for longer than men remembered. She knew every sound it made, every stroke of a fish, every shift of tide. What she heard was neither. It was rude splashing of mortals. Long ago she had made it very clear that this was her cave and she was not to be disturbed! It had been a while since she had dragged some filthy fisherman to his death for murdering the denizens of her beach. Clearly it was time to remind them why they feared this cove.
She eased through the water, her body made, no, cursed for it. Her upper body was similar to a human woman's. Long, dark, but slightly green hair. Ample breasts and wide thighs. But it was there that the resemblance faded and the curse began. Instead of legs she had large dark blue tentacles. No longer the agile fin of the mer people. She was something in her mind more horrible. She had fled from their horror and lived in this cave since the goddess had cursed her for the unwanted love of a god.
She slid forward towards the light and sound when she spied them. Mortals but not fishermen. In fact, what they were doing had little if anything to do with the creatures that swam around them in the water! She had seen the mortals before but it was usually only the men she saw up close-the women hiding on the shore or screaming on the cliffs, mourning their dead sons and husbands. For the first time she saw one, and even got to see it unclothed. The man too was different. He had dark hair but his face was smooth and free of hair, as was most of the rest of his body. He did have tufts under his arms and between his legs at his-what was that?
In the mer people, their love organs were kept behind a slit in their main trunk and nearly invisible until in use; exposed only when they bred and always in privacy. But this land dweller's was clearly always out and it was very clearly large and erect. Beneath it was a strange sac that as they caressed the female would touch from time to time. The female herself was also unusual. She too had hair, shorter and curly but still down to her neck and reddish. Her arms and legs were also bare but there was also a tuft above her pubis. It matched the hair on her head but was curlier. Her breasts were smaller than Sulara's own but firm, almost pouty. She was as head shorter than the man but had round thighs.
They kissed as the mer people do, but she also reached down and stroked gently his member as he grabbed the area behind her legs. Sulara just now noticed how it looked, split but pleasantly shaped. The mortal man's hands grabbed and squeezed it lovingly and the woman giggled.
Strange feelings came over Sulara as she watched them. She felt a fire start inside her belly and an odd tingling below where her tentacles came together. She silently swam closer.
Deana broke off her kiss and scampered up to the edge of the water then laid back, resting on her elbows. She spread her thighs invitingly. Kit dove into the water and worked his way up the sand bringing his head between her legs. From there he crawled the last few inches, a devil may care smile on his face and buried his mouth in her vagina. She squealed with glee and her legs came together revflexively, "Oh yes-oh Kit!" she cried as his tongue expertly worked first her vaginal lips and then her clitoris. She jerked spasmodically as he hit all the right places and waves of pleasure washed through her. They were so distracted in their lovemaking they did not even notice the strange being next to them.
Deana orgasmed with repeated cries of "Uh! Uh! Uh!" then shuddered. Able to take no more she reached down to get kit to stop. She heard the sigh next to her then turned, surprised to see Sulara there. Deena's orgasm had drawn Sulara from the shadows-her curiosity overcoming her desire to remain hidden. Kit, seeing Deana stare looked over and saw a beautiful woman with pale blue skin topless. They both let out an unconscious sigh; Deena buoyed by her fresh orgasm and Kit by his unsated lust.
